11.2 DISPLAY
The display by default shows the charging current during the charge cycle. The
display may be changed to show voltage, time or Amp-Hours by pressing the
FUNCTION button. The display may show additional messages as the charge cycle
progresses or a fault occurs.
11.3 PAUSE PUSH BUTTON
This PAUSE push button will halt the charge cycle. The battery can then be safely
unplugged for up to 10 minutes. If the battery is still connected after this time, the
charger will continue with the present charge cycle.
11.4 SMART START STAGE
The charger begins the charge cycle at the high rate current and continues until the
gassing voltage is reached. If the time to reach the gassing voltage level is equal to
or less than 2 minutes, then the charge cycle will be suspended and a battery
voltage test to determine if the battery was in a sulphated or heavily discharged
condition will be instigated.
During the suspension, the decay in battery voltage is monitored. At this time, the
display will show VPC only. If the battery voltage decays quickly the battery is
determined to be sulphated and the charger will continue to Stage 1 High Rate or I1
current level with a ‘sulphated battery’ fault set. If the battery voltage does not fall
quickly, the charger will terminate and Auto Balance stage will be entered.
If the time to reach the constant voltage level is greater then 2 minutes and less than
45 minutes, the gassing voltage is maintained until the current level is equal to the
Finish Rate or 32% of the maximum output current. Charge will then terminate and
Auto Balance stage will be entered.
When the constant voltage stage U1 is entered then the display shows ‘StSt’
alternating with current.
When the Auto Balance stage is entered, the green LED will be illuminated and the
display will show ‘StSt’. The FUNCTION button can select charge information.
